Following her release from prison in early November, Teen Mom star Amber Portwoodhas shown signs of being a different woman.

In her first post-prison interview, she exclusively revealed to In Touch that before prison—where she spent more than a year—she “never thought about [her daughter] Leah,” because she was addicted to drugs and didn’t think about anything else.

Now, in a new interview with Dr. Phil—Amber’s first TV interview since her Nov. 4 release—she’s painting a picture of just how bad things were before she was locked up.

“Every time you see me on [Teen Mom], I am high, “ she told the television doctor, revealing just how much her substance abuse problem escalated. She continued by saying that the Dr. Phil appearance marked her first time being sober on stage.

Of course, Amber’s world was forced to change her ways in June 2012, when she was sentenced to five years in prison after failing to complete court-mandated rehab.
